如果不使用 yield，这将如何编写？

Question

我尝试过多次尝试替换 yield 但都失败了，但我似乎没有成功，目标是具有相同的功能，没有 yield。

def calcPi(limit):  # Generator function
    """
    Prints out the digits of PI
    until it reaches the given limit
    """

    q = 1
    r = 0
    t = 1
    k = 1
    n = 3
    l = 3

    decimal = limit
    counter = 0

    while counter != decimal + 1:
        if 4 * q + r - t < n * t:
            # yield digit
            yield n
            # insert period after first digit
            if counter == 0:
                yield '.'
            # end
            if decimal == counter:
                print('')
                break
            counter += 1
            nr = 10 * (r - n * t)
            n = ((10 * (3 * q + r)) // t) - 10 * n
            q *= 10
            r = nr
        else:
            nr = (2 * q + r) * l
            nn = (q * (7 * k) + 2 + (r * l)) // (t * l)
            q *= k
            t *= l
            l += 2
            k += 1
            n = nn
            r = nr

只需定义一个列表并收集数字：

def calcPi(limit):  # Generator function
    """
    Collects the digits of PI
    until it reaches the given limit
    """
    pi = []
    ...

    while ...:
        ...
        # yield n
        pi.append(n)
        ...
            #break
            return pi

如果不使用 yield，这将如何编写？

How would this be written without using yield?

python

pi

yield
